Today's diesel engines are known for their reliability, power, and fuel economy. One of the most popular diesel engines is the Cummins 6.7-liter engine first used in 2001 Dodge trucks however it is currently found in many workhorse applications including medium-duty commercial trucks, buses, and military vehicles.
The engine is a six-cylinder, turbocharged diesel engine built in the United States. It is a successor of Cummins 5.9-liter engine and can be found in Cummins specifications B, N and R.
Introduced in 1997 to replace Cummins 4B diesel engine, it featured high pressure common rail fuel injection, aluminum heads with an iron block construction, roller cam followers with four valves per cylinder and reed valve induction system . The power range for this line of engines was from 165 to 300 horsepower at 3100 rpm or 500 ft lbf of torque at 1600 rpm depending on application while delivering up to 20 percent better fuel economy than previous generation Cummins 5.9 liter engines.
The Cummins-6.7-liter engine meets the latest emission regulations through a combination of advanced injection timing and turbocharging while providing better fuel economy and performance. The engine can be found in Cummins specifications B, N, and R.
Since its first application, Cummins 6.7 liter engine was often modified and upgraded by third party companies to increase power output for heavy-duty applications such as medium-duty commercial trucks, buses, military vehicles, etc., e.g., S&B Cold Air Intake System for 75-5092 which helps it produce up to 500 horsepower at 1600 rpm or 1000 ft-lb torque at 1200 rpm allowing to pull more weight on any terrain or climb hills easier without compromising economy or performance.

The scooped design allows more air intake for great cold air intake systems, which means that you get more horsepower and torque from your Cummins engine. It also reduces turbo lag because of the larger volume of incoming air to the turbocharger.
The material used for the pipe and hose also affects the air flow. A good quality product should be made of aluminum or stainless steel so you can expect improved airflow. The ideal distance between the filter and turbocharger is around 12 inches to ensure enough air flow.
You have to check all the types of cold air intake filters available before making a purchase. The foam filter is the cheapest option, but it traps dust particles and reduces airflow. It also needs replacement two or three times more frequently than other kinds. Paper filters are good for trapping dirt particles, but they don't let enough air pass through them. This leads to reduced performance, especially when the engine is under load. You should go for a washable polyester or cotton filter because it does not require replacement and keeps dust particles at bay while letting air pass easily.
Air Intake kits for your Cummins diesel engine can give you up to 19 horsepower and 50 foot-pounds of torque more than the stock air intake system. The improved airflow enhances the performance, resulting in better mileage and reduced turbo lag that gives you a feel of a V8 engine.
You should check the installation method before choosing a product. The best kits are easy to install and usually include detailed instructions that anyone can follow.
Now you know all about air intake filters for your Cummins diesel truck engine. Do not buy any filter without considering these factors, or you'll end up with a low-performance system that does more harm than good.
A lot of factors go into making an excellent air intake kit for Cummins trucks, and it is very important that you filter out the ones that don't work well or just aren't worth buying. For example, there are several different types of air filters and numerous other features that will affect how your engine operates.
A cold air intake is a type of air filter that allows for cooler, denser air to flow into the engine. As opposed to warm air intakes, which take in warmer air from around the engine bay area, cold intakes are usually mounted high up on the engine's intake manifold where colder air is present. This results in an overall cooler temperature for the engine, which in turn results in better combustion and can add some power.
The cold air intake kit for the Cummins diesel engine allows for cooler, denser air to be drawn into the turbocharger. This results in better combustion and more power out of the engine. It also reduces turbo lag because of an increased volume of the intake air.
Turbochargers work best when operating at an optimal temperature. The 5.7L Cummins engine uses a liquid-cooled intercooler to lower the intake air temperatures, but this still isn't enough to supply the turbo with cool enough air for maximum efficiency. This is where cold air intakes come into play by drawing in massive amounts of cooler air and allowing the turbo to operate at a more optimal temperature.
Clean your cold air intake once every 30,000 miles or so. Doing it more frequently may be a hassle but is fine if you have the time and dedication to do it. Make sure that you're using a good cleaning agent to get rid of any grime that might build up in between cleanings.
Just like any other aftermarket modification for your truck, the intake system will make it louder. Some drivers don't mind the increased sound levels but others may find this annoying. Make sure to consider this before you modify your Cummins diesel engine with an intake kit.
In short, no. Cold air intakes have been designed to work on their own without the need for a tuner. Sometimes tuners are necessary if you want to add more power or make some other changes but generally speaking you can run a cold intake without a tuner and it will not pose any problems at all.
Generally speaking, you can expect to see at least 5-10 horsepower increase when installing an intake system onto your Cummins engine. Note that this is just general information and your particular mileage may vary depending on the type of filter that you've installed, how much work has been done on the truck itself in terms of other modifications, etc.
A TBI spacer is a type of modification that you can do to your Cummins engine if you want to increase power and torque. Basically, it involves taking material away from the throttle body and replacing it with spacers that will reduce the distance between the throttle body and intake manifold. This makes for better fuel atomization (and therefore combustion) and more power out of the engine.
You can keep track of your air intake filter by checking it every few months for any signs of dirt, grime, or ash. You will need to clean this out once in a while, most likely every 30,000 miles or so depending on how often you drive your vehicle.
To properly clean a cold air intake system, just follow the instructions that come with your kit or search for how to best do this online. There are tons of resources available online, including some videos as well as step-by-step instructions from other Cummins engine users. Make sure to follow all safety precautions before you start working on your cold air intake system.
Yes, cold air intakes work on the Cummins engine! However, you will need to get any modifications for your 6.7L done before installing your intake kit. This includes getting it tuned so that the system will function properly and without any problems. Make sure to get all of this done before modifying your truck or else you may risk damaging
Absolutely! Cold air intakes are one of the most popular modifications for diesel vehicles, including the 6.7L Cummins engine. Many drivers notice a huge difference in power and performance thanks to cold intake mods so it's definitely worth considering if you want your truck to be more powerful, efficient, and responsive all at once.
All of the above questions have been answered in a very detailed manner so you should feel much more confident about making a decision on whether or not to get yourself an intake kit. Your Cummins engine is sure to run better and be more responsive once you do this, especially if you've installed other mods like tuners, exhaust systems, etc.
Always make sure to follow all instructions that come with the cold air intake kit itself as well as any other guidelines for modifying your particular Cummins engine. Make sure you are aware of how to use it safely and within the limits of all safety precautions. This will allow you to get more power, enjoy better performance, and even gas mileage if you make all the right decisions and take the proper safety precautions at all times.
Good luck with your Cummins engine's cold air intake system!
